A Little Amateur Astro­spectroscopy

After an intermission of over ten years I restart my
activities in astronomical spectroscopy. Now I use a LHiRes
III mounted on the Meade 16" SC at the Volkssternwarte
Neumarkt or on my Celestion C11 at home.

The new website will grow as new observations are done. I
open with an article about the rigidity in the LH III.
